Hi, I am using the MCB900 with the P89LPC932 microcontroller and I wanted to install an external crytal. After having it installed, I went to Flash Magic and selected from the ISP menu the "Device Configuration" option and then I selected "slow crystal...3 to...KHz" After doing that and trying to run the microcontroller, it does not work at all. The board is not working right. Does any one know what happened there. any ideas... I put a new micro controller, but still is the same.
It sounds like a problem with synchronizing the baudrates from the PC and from the MCB900. Maybe the XTAL you selected can't generate a standard baudrate. Jon
Thanks Jon for getting back to me. I thought it was the crystal, so i took it off the board. Now, I have working w/out it , but it still does not work. Thanks J.C.
